Over the past 36 years, this approach has resulted in the development of numerous useful processes in the areas of wastewater treatment and conservation, solid and hazardous waste treatment, and other specific unique unit processes. Many of these developments have resulted in patents, or become widely accepted.

1. In the late 60's, Hydronics conceived and patented the BioCarb process, which generally employed the use of powdered activated carbon as an adjunct to mixed liquor in the activated wastewater treatment process. This idea has since become widely practiced.

2. Hydronics designed and patented a process for the electrolytic treatment of high nitrate bearing wastewater. This successful process was adopted and implemented at full scale by a major NiCad battery manufacturer. Today it still has significant application as a viable treatment technology.

3. In the early 70's, Hydronics pioneered and developed the concept of centralized commercial hazardous waste treatment facilities. The heart of the system was a 150MM BTU liquid injection incinerator. Supporting unit processes were sulfuric acid pickle liquor treatment and biological treatment of aqueous organic wastes. Concentrated waste solvents were blended and incinerated at high temperature/high residence time. These facilities were among the first to be regulated for the destruction of PCBs, and the biological waste treatment system was the first of its kind. This concept resulted in the construction and operation of four major facilities, three of which are still in operation today.

4. Hydronics developed a patented process for the recovery of elemental selenium for a major photocopier manufacturer. This process was put into full scale operation at two facilities.

5. Hydronics conceived of and developed a series of unit processes for the economical treatment of acid mine drainage containing marketable recoverable heavy metals such as copper and zinc. This process was superior to existing practice in producing minimal waste products, acceptable pH and TDS discharge, and marketable metal powders and salts.

6. Over the years, Hydronics has had to necessarily engage in creative laboratory practice to support our and our clients' developmental work. This has resulted in analytical methods development in a broad range of areas and applications.
